Figures & Tables

Fig.1

Three-electrode cell. WE: working electrode, Re1. reference electrode, CE: counter-electrode.

Fig.2

Frequency and amplitude of the interpolated points. ωp: ${{\omega }_{p}}:$central frequency of the dispersion.

Fig.3

Resistance (Black) and reactance series equivalents (Steel Blue) of the EEI versus frequency for AISI 304 stainless steel electrode polished with sandpaper #180 in NaCl 0.9% solution. Overpotential applied = 10 mV.

Fig.4

Reactance series equivalent of the ZEEI versus frequency. Experimental data (◼) and applying the KK equation (4) to the experimental data (x).

Fig.5

Resistance series equivalent of the EEI impedance. Expanded dataset (ο) and Experimental data (∙).

Fig.6

Reactance series equivalents of the EEI versus frequency. Experimental data () and applying the KK equation (4) to the expanded dataset (x).

Fig.7

Percentage change of Zp′′(ΔZp′′%)  versus ωmin. $Z_{p}^{\prime \prime }\left( \Delta Z_{p}^{\prime \prime }\text{%} \right)\,\,\text{versus}\,{{\omega }_{min}}.$Red point: case without extrapolation (figure 4). Blue point: ΔZp′′%=−1. $\Delta Z_{p}^{\prime \prime }{\text%}=-1.$
